My system: RX-V430 Yamaha receiver KSF 8.5 mains KSC-C1 center IC 650 rears KSW 10 sub Digital cable, JVC DVD, Sony VCR, Panasonic 36" TV Primary use of system is home theater, TV watching...secondary is music. I have had everything set up for a year or so. Overall very good sound for loud movies (Gladiator, Private Ryan and such), but I am no audiophile, just a lay-listener with a limited budget. My questions: I have noticed a hum from the subwoofer. Any suggestions? I got the manual out, it suggests that the cable-TV hookup could be the cause of the hum. I checked, it doesn't seem to be the problem. Looking closely at the manual for the sub brings me to my second question. I have this sub hooked up with a Monster Cable "sub" cable with a Y cable from the "subwoofer" outlet on the receiver. Should I also have it connected with speaker wire to the main speaker outlets on the receiver? The diagram seems to suggest doing both. When I bought the sub the salesman only suggested using the cable. Would I gain anything by using the speaker wire, or should I just sit tight and focus on fixing the hum? Any help appreciated --
